No, sorry! Nothing happened at all, I popped it with a sterilised pin and tried to squeeze but nothing came out at all, so he spent yesterday with dettol on it swapping over with zinc paste now an then too but still nothing has changed, head seems to have disappeared if anything.

Hes just gone to the dr's now so will report back later, he is under strict instructions though not to let the dr do anything without me being there (rubs thighs!)
